The price p (in dollars) and the demand x for a particular clock radio are related by the equation x = 2000 - 10p. (A) Express the price p in terms of the demand x, and nd the domain of this function. (B) Find the revenue R(x) from the sale of x clock radios. What is the domain of R? (C) Find the marginal revenue at a production level of 1200 clock radios. (D) Interpret R'(1500) = - 100.00. (A) p=p(x)= D The table to the right contains price-demand and total cost data for the production of projectors, where p is X p($) C($) the wholesale price (in dollars) of a projector for an annual demand of x projectors and C is the total cost (in 310 561 109,000 dollars) of producing x projectors. Answer the following questions (A) - (D). 450 395 125,900 630 166 155,000 820 93 188,000 . . . (A) Find a quadratic regression equation for the price-demand data, using x as the independent variable. y= ] (Type an expression using x as the variable. Use integers or decimals for any numbers in the expression. Round the coefficients to seven decimal places as needed. Round the constant term to three decimal places as needed.)
